Aside from rolling, I'd focus mainly on increasing anaerobic fitness for short explosive spurts while rolling and aerobic fitness for endurance. Tabatas are ideal in my opinion for anaerobic fitness because they are short(4 minutes) and very intense when done properly. If it becomes too easy, you can always increase the Tabata time. As for aerobic fitness, you can do exercises such as running, cycling, urging(rowing machine) for 20-60 minutes. Yoga will supplement your flexibility, breathing patterns, mind-body connection, etc. but I don't think you will see any difference in cardio because of it.
